辣根过氧化酶(HRP)示踪法是70年代初出现的一种新的神经解剖学研究方法,由于它具有许多前所未有的优点,在短短数年内便广为国外神经学者所采用,做了大量工作,把神经学研究工作大大向前推进一步。自60年代中期以来便有人报道:某些物质如氚组氨酸(~(-3)H-histidine)、某些氨基酸、钌红(Ruthenium Red)等外源性的大分子物质可以透过神经纤维进入轴索,并沿轴索传递至胞体。过氧化酶示踪法最早是被用来观察大白鼠及小白鼠 Horseradish peroxidase (HRP) tracer method is a new method of neuroanatomy appearing in the early 1970s. Because of its many advantages, it has been widely adopted by foreign neuroscientists in a few short years. A lot of work, the neurological research work forward one step forward. It has been reported since the mid-1960s that exogenous macromolecules such as tritiated histidine (~ -3 H-histidine), certain amino acids, Ruthenium Red, The fibers enter the axon and are transmitted along the axon to the soma. Peroxidase tracer was first used to observe rats and mice
